the biggest thing to me, in terms of server load, is that reddit does not need to host videos/images. It’s a link aggregate.
I’m only a layman in this particular field, but I imagine it’s a lot lighter on resources to direct people to sites streaming video than to host and serve it all yourself.
Text and database entries are, indeed, Vastly lighter on resources (compute and bandwidth). Bandwidth cost for text is practically free. Managing voting is surely not easy though; every single vote is an additional database entry which means that they cost money to store. Then the vote sorting algorithm has to run pretty frequently. Comments themselves are probably nothing compared to the votes.
But managing voting and sorting is a one-time-cost. Reddit doesn’t let you vote on old things which means that they can completely discard the votes and keep the totals and never resort ever again. They have no real ongoing costs there.
